Improved modified fast Haar Wavelet transformation [MFHWT] based visible watermarking

Abstract

With the explosive growth of internet technology, many innovative applications requiring exchange of large amount of data have become feasible and hence security of data have become a critical issue. In this paper, a robust and secure visible image watermarking algorithm is purposed. This purposed algorithm is based on Multi Wavelets with Modified fast Haar Wavelet transform [MFHWT]. MFHWT is the latest technique used for wavelets transformation which is used to perform image analysis at faster rate than previous techniques. The main idea of the purposed algorithm is to decompose the original image into fine scale sub bands using MFHWT according to the size of the Watermark. In this algorithm, the obtained watermarked image. In this algorithm has very high Peak Signal to Noise Ratio [PSNR].
